A book audiogram is a short audio clip from any part of your book — packaged as a shareable video for social media. Unlike Audible's automated samples, you choose which passage best represents your book.
CoHarmonify offers a free audiogram creator that requires no account. You paste an excerpt, choose an AI voice, and receive:
The whole process takes under 60 seconds. Try the free audiogram creator →
Yes — through our voice cloning feature. You record audio samples of yourself reading, and our system builds an AI model of your voice. Your audiobook chapters are then generated using that model, so the finished audiobook sounds like you narrated it.
Recording samples is always free. Voice cloning generation uses a day-pass credit system:
Credits never expire and stack with additional purchases. One credit covers all generations on a given calendar day.
Not sure if AI voices or your own cloned voice is right for your book? Test the free audiogram tool first — it uses the same AI voices available in the full studio.
ElevenLabs is a voice generation engine — it converts text to speech with high-quality AI voices. It's a powerful tool for generating individual audio clips, but it doesn't provide an audiobook creation workflow.
CoHarmonify is a complete audiobook studio. The difference in practice:
If you need a single voice clip, ElevenLabs works well. If you're producing a complete audiobook and want to distribute it, CoHarmonify handles the full pipeline so you don't have to stitch it together yourself.
Audible and most audiobook platforms generate samples automatically from the first few minutes of the uploaded file. This means listeners always hear the foreword or slow-paced introduction — rarely the part of the book that would actually hook them.
CoHarmonify's audiogram tool lets authors choose any passage from any chapter to share as a promotional clip. Instead of relying on the platform's automated sample, you pick the scene, quote, or insight most likely to resonate with your target readers — and share it directly on social media before listeners even visit a purchase page.
